Stathmin dynamics modulate the activity of eribulin in breast cancer cells

open access: yesPharmacology Research & Perspectives, 2021
Stathmin, a phosphoprotein that modulates microtubule dynamics, is highly expressed in breast cancer cells. Eribulin, a microtubule‐depolymerizing agent, is used to treat patients with advanced breast cancer.

Microtubule assembly governed by tubulin allosteric gain in flexibility and lattice induced fit

open access: yeseLife, 2018
Microtubules (MTs) are key components of the cytoskeleton and play a central role in cell division and development. MT assembly is known to be associated with a structural change in [Formula: see text]-tubulin dimers from kinked to straight conformations.

Polymorphic Dynamics of Microtubules [PDF]

open access: yesarXiv, 2010
Starting from the hypothesis that the tubulin dimer is a conformationally bistable molecule - fluctuating between a curved and a straight configuration at room temperature - we develop a model for polymorphic dynamics of the microtubule lattice. We show that tubulin bistability consistently explains unusual dynamic fluctuations, the apparent length ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

open access: yesAdvanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Critical appraisal on mitochondrial dysfunction in Alzheimer’s disease

open access: yesAGING MEDICINE, Volume 5, Issue 4, Page 272-280, December 2022., 2022
Amyloid plaques deposit on neurons in case of Alzheimer's Disease. Mitochondria play a vital role in pathogenesis of Alzheimer's Disease. Mitochondrial dysfunction can lead to formation of mPTP, alteration of complexes 1,3 and 4, deficits in bioenergetics with impaired mitochondrial biogenesis. Abstract It is widely recognized that Alzheimer's disease (

Characterization of Motility Properties of Kinesin-Driven Microtubules Towards Nano-Scale Transporter: Focusing on Length of Microtubules and Kinesin Density

open access: yesJournal of Biomechanical Science and Engineering, 2008
Kinesins, biomolecular motors moving along microtubules (MTs) in cells, can potentially be utilized as nano-scale transport systems with an inverted gliding assay, in which the MTs glide on a kinesin-coated surface.

Minimal Mechanisms of Microtubule Length Regulation in Living Cells [PDF]

open access: yesarXiv, 2023
The microtubule cytoskeleton is responsible for sustained, long-range intracellular transport of mRNAs, proteins, and organelles in neurons. Neuronal microtubules must be stable enough to ensure reliable transport, but they also undergo dynamic instability, as their plus and minus ends continuously switch between growth and shrinking.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Exploitation of Cellular Cytoskeletons and Signaling Pathways for Cell Entry by Kaposi’s Sarcoma-Associated Herpesvirus and the Closely Related Rhesus Rhadinovirus

open access: yesPathogens, 2012
As obligate intracellular pathogens, viruses depend on the host cell machinery to complete their life cycle. Kaposi’s sarcoma-associated herpesvirus (KSHV) is an oncogenic virus causally linked to the development of Kaposi’s sarcoma and several other ...
